FRANK s. MEES, or Lxnn, MASSACHUSETTS, Ass reNoR To NORTH AMERICAN CHEMI- CAL coMrAnY, or BOSTON, MASSACHUSETTS, A CORPORATION or MASSACHUSETTS METHOD 'OF OUTLINI NG MCKAY SHOES Application filed December 31, 1927. Serial No. 243,845.

In order to make a neat McKay shoe, having a first class appearance next to the outer sole, the edge of the upper where it is bent over the innersole is edged, creased, or outlined by an ironing process with a hot iron applied and operated the same as one would iron a garment. This has always'been done as a separate operation requiring therefore a separate operator, a separate operating stand and a separate operating .tool. My present invention eliminates this extra operator, stand, and tool. At the same time that the bottom filler is laid and spread in the shoe-bottom cavity and the pleated or lapped edges of the upper are waxed, I outline the edge of the upper and I accomplish all this simultaneously with one and the same tool and operation. The McKay shoe might be called the poor mans shoe, and therefore I 29 consider that this material saving in time,

labor, and factory equipment is a material contribution toward further reducing the cost of this important class of shoes.

Further advantages of my invention will be pointed out in connection with the following description taken with reference to the accompanying drawing, in which I have illustrated the invention sufficiently to make the same clearly and readily understood.

In the drawings is shown a cross-sectional View of one form of McKay shoe showing the single tool, before mentioned, for accomplishing the outlining of the upper at the same time with the spreading of the filler and waxing of the inturned edges of the upper to render the shoe anti-squeak.

The upper 1 of the shoe on the last 2 is pulled over the edge 3 of the innersole 4: in pleats which are tacked or otherwise secured to the innersole as conventionally illustrated at 5. This forms a shoe-bottom cavity 6 between the exposed side of the innersole and the inturned edges 7 of the upper. Then a spreadable filler piece 8 is put in place and flattened or spread to cavity filling position as indicated in the drawing. This spreading is done by a roll 9 electrically heated by a cartridge unit or any other kind of heater 10, and at the same time that the roll spreads the filler it carries some of the wax from the filler over onto the crimped inturned edges 11 of the upper to render the shoe anti-squeak at this pointwhich has heretofore caused most of the squeakingcommon to McKay shoes. It will be understood that. by the'term waxing I mean to include any anti-squeak coating-or applicationwhether of technical waxor otherwise. I make the roll 9 longer than the width of the shoe and preferably slightly flaring as indicated at 12 so that thereby the roll as it goes over the shoebottom outlines the edgeof the upper at the point 13 where it has always heretofore been ironed as a separate operation. This gives the true, straight, neat outlining or sharply defined corner next to the outer sole when the outer sole is later put in position and secured as the final element in the shoe-bottom. 7

It will be understood that heretofore it has always been the practice to apply the filler to the shoe-bottom and secure it in place.

Then the shoe has, as aseparate operation,

been painted or otherwise waxed alongthe reglon 11, and then taken to another stand in the factory where another operator was provided with an electric ironing'tool of the same nature as a laundry fiat-iron and ironed back and forth. I eliminate all these extra steps and tools. and accomplish the entire operation in all three particulars simultaneously by one and the same tool and one and the same operation. By simultaneous I do not mean necessarily torestrict the accomplishment of the three preferable features of filler spreading, antisqueak waxing, and edge outlining by a single forward or back movement of the roll. No two shoes are exactly the same, as the innersoles differ, the upper leather differs, and, in fact, everything about the shoes differs necessarily in one shoe from another shoe. So it may naturally be found that the operator has to tip his shoe a little with reference to the roll in order to make the outlining true and correct, and especially if astraightroll rather than a flaring roll is employed. Also different operators have their own peculiarities of preference andone operator may prefer to move the shoe with reference to the roll first forthe filling operation, devoting his strict attention to the bottom cavity to see that he gets the filler spread accurately and then he simply swings the shoe around in contact with the roll for the edging operation. Thus, in any case, the outlining or edge ironing is accomplished the same. time as the filler laying 'and by the same tool, so that by my process an extra tool is rendered unnecessary and likewise the usual separate ream-and p t -Op tioni It will be observed that I preferably slightly concave the roll Q at 14; seas to arch the spread filler slightly. This is for the purpose of providing. slight, excess oigfiller so that when the sole is laid and secured to the upper andinnersole in usual manner, and then subjected to the bottom leveller, the pressure of the latter will force outthis excess ofbinder into thepleats of-the intnrnedupper and between saidupper and the outer-sole so as to unite all the" parts of the bottom to function substantially'as a single unit.
